I have a shallow well pump in my basement that was previously connected to the well with about 80 feet of 1" plastic pipe. I recently replaced about 30' of this plastic pipe in the basement with 1" rigid copper to get it up off the floor. I now have a very loud and sharp water hammer when the pump shuts off. Previously the plastic would have a slap in it when the pump shut off. I only have a foot valve at the bottom of the well. I am considering putting in a Hydra-Rester in the suction line between the pump and the start of copper pipe. Will this work? Is there a better place to put it? Thanks.
